To all whom it may concern.-

Be it known that I, HENRY W. YERINGTON, of Jersey City, in the county of `Hudson and State of New Jersey, have invented a new and useful Improvement in Apparatus for Burning Liquid Fuel, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification, and-in which- Figure l represents a plan of an apparatus for burning liquid fuel constructed in accordance with my improvement, and Fig. 2 a longitudinal vertical section taken as indicated by the line w w in Fig. 1.

Similar letters of reference indicate corresponding parts.

My improvement in apparatus for burning liquid fuel consists in a novel safety arrangement of the oil-tank by surrounding it with an air-jacket, through which a current of cold airis made to pass in its way to admixture with the gas prior to its entry within the burners. Also, the invention includes, in combination with such an arrangement, a steam-jet or jet-pipe, to promote the draft or current or air, as described; likewise, a novel mode or disposition of parts for generating the gas, and intermediate gas-pipe connection with the pipe which conducts the air to mix with the gas; also, a certain construction of distribution and mixing chambers at the ends of the burners; and, under a fire-grate or gridiron arrangement of burners, a certain oblique disposition of slots for the flame, and whereby the outside air which supplies the flame is allowed to pass not only under but between the flame.

As constructed and arranged, this my improved apparatus is applicable, among other purposes, to the heating or working of steamboilers.

Referring to the accompanying drawing, A represents the oil-tank, to which a is the supply or feed pipe, and b the discharge-pipe, for generation ofthe gas, and o a valve to permit of the escape of any gas forming in the tank. Said tank is arranged within a jacket, B, having an intervening air-space to or around the tank. This jacket, which is closed by a lid or cover, is provided with an air-supply pipe, d, at or near its top, and delivery or suction pipe C on the opposite side, at or near its bottom.

E E are the burners, of any suitable number, and formed of tubes disposed to lie'horizontally and parallel to each other, Vor thereabout, with ame or gas-jet orifices in their sides, produced by oblique slots e, by which construction and arrangement of the tubes or burners the outside air to keep up combustion is not only caused to pass up from beneath or under the flame, but also between the latter, and a better heating effect produced. These burners E E are connected at their opposite ends with air and gas mixing and distributing boxes or chambers F F, over partial diaphragms f. The suction air-pipe C. connects with a pipe, G, open at its ends to the boxes E E below the diaphragms f; and, by way of promoting the supply of air through said pipes, and keeping up a suction on or through the jacket B, steam is supplied from the boiler by a pipe, H, which is made to circulate over or through the ames from the burners, and finally made to terminate in a jet-nozzle, g, disposed or set so that the steam issuing therefrom will flow in the direction of the current of air, whereby the draft through the air-j acket is quickened, which serves to keep the tank A, though placed in comparative proximity to the burners, cool, and protects it against explosion by the over-heating of the oil, also whereby any gas forming in the tank and escaping by the valve c is passed to the burners. This is much'superior to walling or incasing the tank in solid material.

The gas is generated and mixed with the necessary quantity of atmospheric air, irst, by a pipe or pipes, I, connecting with the oil-discharge pipe b, and made to circulate over or in proximity to the burners, the heat from which generates the gas, Vsaid pipes opening` intothe boxes E E, at or near their oneend, above the diaphragms f, and, furthermore, connecting, by an intermediate branch or pipe, J, with the air-pipe C.

The pipes I, after entering the boxes E E, as described, are bent or turned to run the length of said boxes, and perforated, as at s, opposite each burner, to supply the burners with gas, which, by the construction of the boxes E E and supply of air thereto by the pipe G, also by connection of the pipes I with the pipe C bythe intermediate branch J, is most thoronghly admixed with air, and a regular distribution of the gas thus mixed or charged to the burners effected.

In Warm climates, and where the apparatus is used on shipboard and the vessel is standing or lying at anchor, the pipe C maybe disconnected from its combination with the burners, and be connected With the smoke-stack, for the purpose of keeping the tank cool.

What is here claimed, and desired to be secured by Letters Patent, is

1. The combination, with the oil-tank A, of the air-jacket 1B, having inlets and outlets d and G, for operation in connection with the burners of a liquid-fuel apparatus, substantiall5r as specified.

2. The combination of the oil-tank A, air- C, substantially as shown and described.

` 5. The tubular burners E E, arranged essentially as specified, and provided with oblique jet orifices or slots e, as herein set forth.
